Linked Server problem on Transaction Usage???

Question

Hi,
I am using SQL Server 2008 R2 and we have a linked server connection to Oracle 11g. We have a table on Oracle thats why we need to do some CRUD operations on both servers. I got this error while trying to update/insert in both servers in a transaction as follows. How can I fix this???
Best Regards.
The operation could not be performed because OLE DB provider "OraOLEDB.Oracle" for linked server "***" was unable to begin a distributed transaction.
OLE DB provider "OraOLEDB.Oracle" for linked server "***" returned message "New transaction cannot enlist in the specified transaction coordinator. ".
Sample code:
conn.Open()
myTransaction = conn.BeginTransaction()
'This is ORACLE
Dim comm As New Data.SqlClient.SqlCommand("UPDATE [***]..[**].[***] SET ApprovedBy=@approvedBy,ApproveDate=@approvalDate,Approved=@approved, StatusId=@StatusId where RequestID=@requestID", conn)
'Add to Transaction
comm.Transaction = myTransaction
comm.Parameters.AddWithValue("@approvedBy", appBy)
comm.Parameters.AddWithValue("@approvalDate", appDate)
comm.Parameters.AddWithValue("@approved", app)
comm.Parameters.AddWithValue("@StatusId", status)
comm.Parameters.AddWithValue("@requestID", reqId)
comm.ExecuteNonQuery()
'This is SQL Server
Dim comm1 As New Data.SqlClient.SqlCommand("INSERT INTO Table1 (DeliveryNo,VendorId) VALUES(@DeliveryNo,@VendorId)", conn)
'Add to Transaction
comm1.Transaction = myTransaction
comm1.Parameters.AddWithValue("@DeliveryNo", deliveryID)
comm1.Parameters.AddWithValue("@ID", ID)
comm1.ExecuteNonQuery()
'Commit Transactions & Close
myTransaction.Commit()
conn.Close()

Open the OUI, click the Installed products button.
You can also infer the info by checking to see if you have "OracleMTSRecoveryService" running in Services, and whether you have oramts.dll in your OH\BIN directory.
